Specification of Letters Patent.

Patented Aug. 22, 1911.

Renewed January 30, 1911. Serial No. 605,554.

To all whom it may concern:

Be it known that .l, llluuur (fl. (luAN'r, a citizen of the United States, and resident of Bayonne, in the county of ,ll udson and State of New Jersey, have invented certain new and useful lln'iprovemcnts in Tracks, of which the following is a specification.

My invention relates to toy cars and particularly to the truck and running gear of same.

The object of my invention is to provide a truck and running gear which will permit of a considerable degree of flexibility vhereby the wheels may have a certain vertical movement relative to each other, without the entire frame being moved in proportion.

A further object is to provide a toy designed to look like a steam locomotive which may be driven by electrical n'icans, and the truck of which is so constructed as to turn sharp curves without leaving the track, and. to pass over uneven rails without any of the wheels leaving contact therewith.

Referring to the drawings which form a part of this specification, l igure 1, is a side elevational view of a car and truck embodylng my invention. Fig. 2, is an inverted plan view of the truck. Fig. 3, a cross sectional view on line X-X of Fig. 2, illusfarting the re ativc movement. of the two sections of the truck frame. Fig. 4, is a cross sectional fragmentary view of: llng. 2 n r I I I V I on line ilk-16 disclosing the constriuztion by means of which the relative movement of the frame is restricted. Fig. 5, is a side View, partly in section, of the front truck, illustrating its construction and means used to limit its lateral swinging movement.

A, indicates the car body, which in the present case is illustrated to represent a steam locomotive having the usual boiler and cab, which is supported on the truck by suitable brackets l5, 15, etc, which in turn are connected to the front frame 0.

Connected to the front frame C by a pivotal joint D, is a rear frame C, which is provided with holes in each side which serve as l'iearingrs for an axle l on which are mounted wheels ll. Supported in similar holes in the frame U is an axle G on which are mounted wheels fl. Connected. to the front frame C is a cross piece it, and just above this a cross piece J, also connected to said front frame. Located below the center of bracket I, is the center of the front truck which comprises two side frame members i l l l lL K provided with openings at each end in which are supported axles, each of which is provided with a wheel IJ IJ at each end. A cross beam ii is connected at ,tltlll end rigidly with the two opposite members K, and is provided with a crescentshaped opening); li through which extends a bolt M, the shank of which is reduced near its middle to form a shoulder M. which abuts the cross beam ll, and the end of the bolt M. is screwed into the (moss piccc J, thus holding the lower end of bolt M. in a rigid manner. Located between the cross beam I and cross piece ii is a washer N which is free to slide on bolt ill, and abutting said nisber and cross beam l is a spring which supports the cross beam l and load thereon at this point. The front truck by reason of the opening K free to move laterally relative to the front frame and to the pivot a 1iredetermined dis tanec, restricted only by the track on which the car as a whole, runs, and by a loosely held link l, which is held at one end by a bracket 1, connected to bracket l), and at the other end by the axle ll which axle is free to slide a certain distance when the truck is turning a curve, the link serving to limit the swinging movement beyond the proper limit.

i (lonnccted to the axle Gr adjacent a wheel ll is a gear wheel S, which is driven by an electric motor T, su 'iportcd from the front frame 0, through a train of reducing; gears ll. The motor is driven by electricity furnishcd by primary battery and conducted to the motor by means of a third rail to a shoe V, and by suitable wires to the motor and return by the two side rails on which the car runs, as will. be readily understood. A

switch for starting. stopping, and reversing the motor is indicated by V.

Connected to a wheel ll is a crank U to which is attached a coupling rod X which extends to a crank on the wheel F and to this last IHHTlOtl crank is commcted a rod Y, the opposite end of which is (winner-ted to a piston rod, Y and cross head Y, these parts being driven by the motor, to imitate a steam driven locomotive. It must be remembered that the joints of the last named connecting rods, etc.. are very loosely made to permit the parts being driven when the front and rear frames are out of alincment with each other by reason of an uneven track or in turning; a curve. When the tracks are not evenly laid, the pivotal jomt D permits the frames C and C with their wheels H and F toswing relative to each other as illustrated in Figs. 3 and 4c whereby all four wheels will remain in contact with the rails, which is one of the most important features of my invention,

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is,

l. in a toy car, a front and rear frame pivotally connected, each frame having holes in which axles are supported and wheels connected to said axles whereby the wheels may swing as set forth, two of said wheels being provided with cranks, and a side rod connecting said cranks and having loose joints for the purpose set forth.

2. In a toy car, a front and rear frame pivotally connected, each frame having holes in which axles are supported and wheels connected to said axles, two of said wheels having cranks, a side rod connecting said cranks and having loose joints, and a front truck pivotally connected to said front frame.

3. In a toy car, a front and rear frame pivotally connected, each frame having holes in which axles are supported and wheels connected to said axles, two of said wheels having cranks, a side rod connecting said cranks and having loose joints, and a front truck pivotally connected to said front frame, and means for limiting its swinging movement relative to said frame.

l. In a toy car, a front and rear frame pivotally connected, each frame having holes in which axles are supported and wheels connected to said axles, two of said wheels having cranks, a side rod connecting said cranks and having loose joints, and a front truck pivotally connected to said front frame and means for driving said car.

Signed at New York in the county of New York and State of New York this sixth day of August, A. D. 1909.
